“Product seems to work for the most part. You must follow instructions that state - wait 20 minutes after drinking before testing. Otherwise, if you've been drinking immediately before testing the results will be off the chart. Like .50”
“I will never go out drinking without this device. The readings are absolutely crucial in determining whether I should or should not be driving. There's no sense in risking a $10,000 DUI as well people's lives when you can know your BAC in seconds. Over .05? Find out easily, and if you are, don't even think about driving.”
“Every so often the the rectangular indicator goes around and around forever, never producing a result. Having no reset button, the only cure is to remove a battery. It would also be nice if there were a last test memory feature.”
“The S80 pro is a sleek, easy to use device. Seems to be very accurate when brand new. However, after I sent it in for the first calibration, the accuracy seemed to degrade after about 50 uses (showed low readings). I sent the item back to be calibrated and BACTRACK was unable to calibrate and sent me a new device. I experienced the same issues after a few calibrations with the new device and BACTRACK sent me another device, this time refurbished. I am still on my 3rd S80 and currently have no major complaints - as long as BACKTRACK keeps sending me accurate devices.”
“I have always used the DMV charts for weight/number of drinks per hour to determine whether I was under the legal limit to drive. However, recently I read an article which mentioned how this method can be inaccurate for certain people like myself. Initially I had problems, getting Flo errors, but finally realized I needed to blow slightly longer, rather than harder. Since I use the unit infrequently, I now carry a copy of the instructions to remind myself how to properly use the unit should I have problems. It's very comforting to know I'm usually well under the legal limit. My designated driver is also happy she doesn't have to bail me out when I fear I'm too close to take a chance.”
